An object of mass ‘m’ is projected from origin in a vertical xy plane at an angle 45° with the x-axis with an initial velocity

An object of mass m is projected from origin in a vertical xy plane at an angle 45° with the x-axis with an initial velocity v0. The magnitude and direction of the angular momentum of the object with respect to origin, when it reaches at the maximum height, will be [g is acceleration due to gravity]
